GATEWAY PROCESSOR

A payment gateway is an e-commerce application service provider service that authorizes payments for e-businesses, online retailers, bricks and clicks, or traditional brick and mortar shops. It is the equivalent of a physical POS (Point Of Sale) terminal located in most retail outlets. Payment gateway protects credit cards details encrypting sensitive information, such as credit card numbers, to ensure that information passes securely between the customer and the merchant and also between merchant and payment processor.
